Summary: In this study, renewable waste sticks/woods were processed into eco-friendly porous activated carbon for renewable energy storage systems. The electrochemical behaviors of the synthesized porous activated carbon were investigated for supercapacitor application. The activation and pyrolysis treatments were found to be crucial in controlling the microstructure, graphitization, and porosity of the activated carbon. The hierarchical porous nature of the activated carbon synthesized at 800 degrees C exhibited excellent capacitive performance, rate characteristic, and electrochemical stability.

Summary: Bio-based porous carbon nanosheets with nitrogen doping showed excellent CO2 capture performance at both low and medium pressure. The pore size and nitrogen functional groups played important roles in the adsorption process. Slit micropores were key factors for low-pressure adsorption, while narrow mesopores were beneficial structures for medium-pressure CO2 capture. Nitrogen doping improved the charge distribution on the carbon surface and enhanced the interaction with CO2, leading to enhanced adsorption and selectivity.

Summary: This study focuses on the production of porous carbon from shaddock peel for environmental treatments. The porous carbon structure and properties were found to be influenced by carbonization conditions and the use of ZnCl2 as a pore-forming agent. By carefully adjusting the carbonization temperature and the mass ratio between ZnCl2 and shaddock peel, the resulting adsorbent showed high adsorption capacity towards methylene blue. This biomass activated carbon adsorbent has potential to be effective and environmentally friendly for water pollution treatment.

Summary: This article studied the effects of salinity and NH4Cl as retarders on the performance of the PAM/PEI polymer gel. The results showed that the effectiveness of NH4Cl to extend the gelation time is significantly reduced in high salinity. Additionally, the gel network greatly loses its gel strength with the increase of salinity, indicating the formation of a weak and vulnerable gel structure.

Summary: Research on bio-based composites is growing rapidly, with natural fibers being commonly used. Natural fibers have advantages such as low cost, biodegradability, and good thermal conductivity. However, the hydrophilic nature of natural fibers can negatively impact the interfacial adhesion between the fibers and the matrix, affecting the properties of the composites. Surface modification using silane treatment has been shown to improve the hydrophobic properties, tensile strength, and thermal stability of bio-based composites.

Summary: The use-and-throw culture of plastic products generates a massive amount of plastic wastes each year, posing a threat to the environment. Conventional disposal methods are no longer the solution, and liquefaction technology has emerged as an alternative method to reduce waste and generate valuable liquid products. Plastic recovery through this method has great potential in reducing dependency on non-renewable energy sources.

Summary: Agricultural wastes, including crop residue, livestock waste, agro-industrial waste, and aquaculture waste, contribute significantly to the accumulation of municipal solid waste globally. In this study, banana peel and avocado seed, two types of agro-industrial waste, were used to develop adsorbents with high carbon content and excellent chemical properties. These adsorbents showed promising adsorption performance for removing mixed dyes from aqueous solutions. The study also investigated the effect of operational parameters and found the optimized conditions for efficient adsorption. The findings suggest that the agricultural waste-based adsorbent synthesized from banana peel and avocado seed has the potential to replace conventional adsorbents from a sustainability perspective.

Summary: This review provides a comprehensive analysis of proactive risk reduction strategies (RRSs) and techniques for evaluating the performance of inherent safety, health, and environmental aspects. Background information is presented on the development and implementation of inherently safer process design and approaches for achieving inherently healthier and environmentally friendlier processes. The characteristics of inherency assessment tools (IATs) based on available information at different process stages are examined, and evaluation methods and historical development of IATs are investigated. The study concludes that there is a need for further research on no-chemical hazards-based IATs to improve the safety level of process plants.

Summary: Over the years, there have been numerous serious laboratory accidents, leading to injuries, deaths, and economic losses, which has prompted increased attention to laboratory safety. However, current safety measures rely too heavily on additional safeguards and pay insufficient attention to reducing hazardous factors at their origins. This study introduces the concept of inherent safety and develops a tool called the Generic Laboratory Safety Metric (GLSM) to minimize laboratory hazards. Through a case study of a university laboratory, it is demonstrated that the GLSM can effectively increase safety levels after risk-based inherently safer retrofitting, providing relatively satisfactory laboratory conditions. This work presents a set of generic solutions and the GLSM as an implementation tool for achieving inherently safer laboratories, contributing to risk quantification and identification of key risk factors for targeted and fundamental safety measures.

Summary: In this study, a dynamic model for batch crystallizer was developed to investigate the eutectic freeze crystallization process of ammonium sulphate (AS) in aqueous solutions. Through process optimization, the significant parameters were identified as initial concentration and initial temperature of cooling fluid, and it was found that AS and ice reached maximum crystallization at 255 K which was close to the eutectic point of AS-water system at 254 K. The dynamic model established in this study demonstrated effectiveness in predicting the crystallization of AS in aqueous solutions.
